摘　　要：To study the indoor air qualities（IAQ）of large commercial office buildings in Hunan province of China and the corresponding improvement methods,the IAQ of a large commercial office building in Changsha in July,2008,is investigated.A questionnaire survey and field tests are used to collect data.According to the data of twelve rooms in this building,objective evaluation and the subjective evaluation of the IAQ are obtained.Almost all of the environmental parameters in these rooms basically meet the standards of the objective evaluation.But the average concentration of carbon dioxide in most rooms cannot reach the value of the cleanliness standards,1 255 mg/m^3.The average acceptability of the IAQ in these rooms is 71%,which is lower than the value of the ASHRAE 55—1992 standards,80%.The proper increase in the wind speed and the indoor fresh air supply can greatly improve the objective evaluation and the subjective evaluation of the IAQ.为了研究中国湖南省大型商业办公建筑室内空气品质环境现状及其改善对策,选取湖南省长沙市某大型商业办公建筑为研究对象,对此建筑在2008年7月的室内空气品质状况进行了调研.采用问卷调查和现场测试的方法收集数据,并基于这些数据对12个房间的室内空气品质进行客观和主观评价.结果表明,这些房间室内空气品质的主要参数基本满足客观评价的标准,但大部分房间的CO2平均浓度未能达到清洁标准规定值1255mg/m3.这些房间室内空气品质的平均接受率为71%,低于ASHRAE55—1992标准规定值(80%).适当地提高空气流速、增加新风量可以很好地改善室内空气品质的主、客观评价.
